PORTABLE'FIRE- EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 364,667, dated June 14, 1887.

Application filed November 8, 1886. ScriatNo. 217,855. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD K. PARKER,

' a citizen of the United States, and a resident of Randolph, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Portable Fire- Extinguishers, of which the following, taken in connection with the accompanying drawings, is a specification.

Thisinvention relates to improvements in portable fire-extinguishers; and it consists in the combination and arrangement of parts, as will hereinafter be more fully shown and described, reference beinghad to the accompanying drawings, where- Figure 1 represents a plan view of the improved fire-extinguisher. Fig. 2 represents a vertical longitudinal section of it, and Fig. 3 represents'a cross section on the line A B shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a is the tank or receptacle for the chemical or other liquid that is used with the apparatus, such tank being tightly closed in its upper end by means of the cover a, soldered or otherwise connected to the said tank a, as is usual in devices of this kind. Through a perforation in the cover a is inserted the short fillingtube b, that is soldered to the cover a or otherwise attached tightly to the same, such filling-tube projecting downwardashort distance below the cover a, as shown in Fig. 2, so that its lower open end shall become sealed by the liquid contents of the tank a when the latter is properly filled, and thus prevent the liquid contents of thetank a from splashing or spilling out during transportation.

1) is a removable screw-cap, by means of which the upper end of fi1ling-tube b is closed after the tank has been filled. Between the under side of the cap I) and cover a, I make on thepipe b a perforation, 1), (shown in Fig. 2,) to allow the air to enter the tank a in the ratio as the liquid within it is displaced.

To the bottom of the tank a is riveted or otherwise secured the Valve'case 0. having the inlet-opening c, VUJVBSGMJ c, ball-valve c chamber 0, delivery ball-valve c and valveseat 0, as is common in apparatus of this kind.

c is a Wire bail or cage for the purpose of limiting the upward motion of the ball-valve c in the usual manner.

(Z is the pump-cylinder, its lower end being screwed tightly into the upper end of valvecase 0, and its upper end projects through a perforation in the cover a, where the latter and pumpcylinder d are united together by solder or other suitable means. d is the cap in the upper end of pump cylinder d, as usual, which cap has a central perforation, through which passes loosely the piston-rod d, having handle at in its upper end and piston d in its lower end, as usual.

(I is a side perforation in pump-cylinder d, below the cap d, to allow freedom of motion of the piston d" during its upand-down motion, and also to permit any liquid that may pass above the piston d to escape from cylinder d without going out the central cap-perforation, and thus preventing the wetting of the hand of the operator.

6 is the air-chamber, the lower end of which is screwed into the upper end of the valvecase c,and having its upper end passing through a perforation in the tank-cover a and soldered or otherwise tightly seen red to the latter at this place.

c is a cap screwed to the upper end of the air-chamber e, and having attached to and projecting through it the delivery-pipe e, a portion of which projects above the cap 6', and to such portion is attached the hose-pipef, as shown in Fig. 2.

The lower end of delivery-pipe c is made bell-shaped or crowning, as shown in Fig. 2, and provided at such point with a series of outward or inclined projections, e 0 between which are the slits, perforations, or openings 0" e, as shown in Figs. 2 and 3. The projections 0 e serve as a guide and stop for the ball-valve c and the perforations or slits e e serve as passages through which the liquid passes from the lower part of air-chamber e .into the delivery-pipe 0 during the downward stroke of the piston d. Tothe exterior of the delivery-pipe e", a short distance above its lower end, is secured a star or cross shaped piece, 6 (shown in Figs. 2 and 3,) the outside dimensions of which are nearly equal to the interior diameter of the air-chamber e, and it serves the purpose to keep the lower end of delivery-pipe e concentric within the airehamber c, as shown in Figs. 2 and 3.

XVhat I wish to secure by Letters Patent, and claim, is

The combination, in a portable fire-extinguisher, of the tank a, the valve-ease c in the bottom thereof, the pump-cylinder d, secured to the valve-case, the vertical stationary airehamber 0, arranged outside the pump-cylinder and having its lower end secured in a fixed position to the valve case at one side the pumpcylinder, the fixed perforated centering-pieee c in the lower portion of the airchamber, the ball-valve c, and the stationary delivery-pipe 0, extending through the outer end of the air-chamber and having its lower end laterally slotted and expanded into a bellshaped month, which receives and guides the ball-valve in its rising movement, substantially as described.

In testimony whereofI have signed my name to this specification, ,in the presence of two subscribingwitnesses, on this 29th day of October, A. D. 1886.

EDWARD K. PARKER.
